It was 1915 when Heinrich Boker & Co. Solingen received the Government order to develop a compact fighting knife that would be especially useful for trench war-fare. After 90 years, Boker is reproducing the original knife blade out of high carbon steel with 0.75% carbon. The pronounced steel crossguard, the wood forearm handle, (designed for a firm and safe grip), and the official tang stamp are identical to the original - as is the cow-hide leather sheath. On the back of the blade, each knife shows its serial number.
